The manufacturers recommended oil is always the optimum choice. If your lifter is tapping due to sludge accumulation causing sticking a high detergent lighter oil is best to "free up" the lifter and restore normal operation. If you lifter is tapping due to accumulated wear the "leak down" rate of the lifter is too high and a heavier motor oil will reduce this rate and quiet the tapping noise. These two different conditions is why you hear people advocating either lighter or heavier weight oil for the same problem. Of couse if the lifter is defective no weight of oil is going to help, it has to be replaced.

Hydraulic Lifters get sludged fail to pump up. Rislone yellow plastic bottle cleans and frees up sticky lifters. This product works wonders and is thinner than regular oil just add a bottle 500 miles before your next oil change. Then add 1/2 bottle with your new clean oil. Drive a while when you get near your next change add the other 1/2 bottle. Just make sure your noise is actually lifter and not something lower in the engine.

If you have a GM small block, and it sounds like only one of the lifters is ticking, it may be that the rocker stud on that lifter is moving up out of its pocket and creating clearance, hence the tick. That is something necessary to fix. If not, then Rislone is a good approach for noisy lifters.

I'm always a fan of LIGHTER oil, especially in colder climates but even if not.
Starting the car after it has been sitting for many hours is when you do the most damage. I'd rather run some lighter oil through there quicker than run heavier oil but have it take longer to get through (and thus be running without oil for longer).
I'd throw some 0w-40 synthetic in it.

Dont listen to those who say to use lighter weight, stay with what the manufacturer recomends, they built the engine, they know whats best for it. Do what those who suggested the treatment said. Find a treatment designged to help unsludge the lifters, and add that to your oil. But, stay with the recomended weight for your vehicle.

it could be a rocker loose.they have stuff in auto zone for valve noises.its usually sludge build-up and not letting the lifter work up and down and also its not building up on oil pressure.
